No. It varies person to person. There are people who have done amazing things and made their stuttering a positive force in their lives. There are also those who are severely negatively affected by it. My recommendation to you is to get a speech therapist, and work on a problem (if there is one) early. Keep socialising with your friends and talk to them about your problem. That will help. If it gets bad, the people in this subreddit care for you! We will always have your back.
